  • To much power for an old bike!!!
I want to preface this by saying the engine is a beast. They mean every bit of 100cc. With a few personal modifications I can push 50mph. My bike is 15 years old, and I'm very quickly having to replace old parts just to keep it up! Make sure to properly space the spark plug, it doesn't come spaced. Here's the down sides: it is a "one size fits all" motor, meaning it is made to fit a large space. It has modifications that come with it that help it fit other sizes, but not always well. I had to make personal modifications to the bike just to help the spark plug fit better. On that note, the carburetor doesn't fit inside the frame, so I have to keep it tilted, causing the engine to bog down. So far I have fixed this with a smaller oil mixture, but doesn't always help. I'm waiting on a piece to fix this, as well as a new carburetor for more power. Fluid filter is very weak, it broke the 3rd day, I had to buy a new one (there like 6 bucks for 2 tho so it's no problem). All in all worth the price! ... show more

  • Not enough install instructions
Should have had vibration dampers included. The throttle cable was too long until it was broke in. Couldn't get it idle high enough. Had to the muffler vibrate loose twice. I added studs bolts with jam nuts. So far so good. Used thread locker on the studs.

  • Works
Well let's say instructions weren't that great , YouTube video made it easier, getting sprocket on was the hard part, ended up having to buy a new bike as engine was too big, next the handle bars, the throttle cable handle grip was broken so unable to try engine out. Waiting on seller to remedy issue. ... show more
